Application March 12, 1938, Serial No. 195,477

28 Claims.

This invention relates to apparatus for heat treating the contiguousends ofv track rails at joints for the purpose of hardening them tobetter withstand the action of the wheels of pass- 6 ing trains, andthereby reduce or prevent what is ordinarily termed batter".

The present invention constitutes an improvement over the rail treatingapparatus disclosed in my United States Patent No. 1,882,417, of Oc- 10tober 11, 1932, and has for its chief aims to render the operation ofsuch apparatus entirely automatic and hence free from the necessity fordependence upon the judgment of the operator as regards the duration ofthe treatment, time of appl cation of the quenching fluid, and thequantity of the latter 18 to be used, so that the rail ends are temperedto the same degree at one joint as at another.

In connection with rail treating apparatus hav- 20 ing the aboveattributes, it is a further object of my invention to secure greatereificiency in the operation of the torch by which heat is applied to therail and at the same time preclude back-firing thereof; to obviate thenecessity for moving the entire apparatus, as heretofore, in order totraverse the torch back and forth over the area of the rail joint beingtreated; and to facilitate the location of the apparatus on the railsfor exact centralization of the torch relative to the rail Joints. 2

Other important objects and attendant advantages of my invention willappear from the following detailed description of the attached drawings,wherein Fig. I is a perspective view of 85 an apparatus for heattreating trails conveniently embodying the present improvements. I
